How to Set Up a Message-Of-The-Day

Edit the message-of-the-day file, /etc/motd, to include announcements or inquiries to all users of a system when they log in. Use this feature sparingly, and edit this file regularly to remove obsolete messages.

1. Become the root role.

   $ su -
   Password:
   #

   ---

   Note - This method works whether root is a user or a role.

   ---

2. Edit the /etc/motd file and add a message of your choice.

   Edit the text to include the message that will be displayed during user login. Include spaces, tabs, and carriage returns.

3. Verify the changes by displaying the contents of the /etc/motd file.

   $ cat /etc/motd
